ENvnLoP-'SEAL Speccation of Letters latent.

Applieation med april 25, 1910. v serial Nq. 557,494.

Tol all whom it 'may concern: l Be it known' that I, NANCY' E. Pn'rrrrr,

Junctiom-in the county of Kimble, kState of Texas, have. invented certain new and useful Improvements in Envelop-Seals; and I do hereby 4declare the following to be a full, clear, and exact description of the invention, such as twill enable` others skilled in the art to which it appertains to make and use the same. i

This inventionv relates to sealing devices for envelops, newspaper wrappers and the like, 'more particularly relating to devices of this character in which oppositely turned convex disks are employed to clamp together the meeting edges of the-wrapper so that the wrapper must be mutilated beyond repair before access to its contentsmay be obtained.

The object of this invention is to provide a sealingdevice which may be securely fastened in positionwith less labor than hitherto, and which will present a smooth surface to the contents of the wrapper so that the same is preserved from linjury during transit to its destination. l

The invention resides in the combination of parts hereinafter more fully `described and claimed. l,

In the accompanying' drawing forming part of this specification, Figure 1 is a perspective view of an envelop equipped with a seal constructed in accordance with' myinvention. Fig. 2 is an enlarged longitudinal sectional view of my improved seal showing the parts assembled for sealing. Fig. 3 is a longitudinal sectional view-through the seal showing the partsV sealed. Fig. L1 is a detail perspective view of one of the shells. Fig. 5 is a detail perspective view of the locking disk. Fig. 6 is a detail perspective view of the mating or guard shell.

Referring tothe parts by their reference characters, 5 designates an envelop having a closingl flap 6. t The seal, comprising the subject matter of this invention consists of an upper convex disk 7 having peripheral fastening prongs 8 which are engaged through theenvelop flap and clenched on the under side thereof as will presently be described.` Projecting axially through the shell 7 is a locking stud9 which is of` suiicient lengthr to projectvthrough thev flap 6 envelop body.

and body of the wrapper 5 and terminates! in a retaining knob 10.

Patented Apr. 9, 1912.

- A convex shell 11 is arranged upon the inf.v

ner face of the body of the envelop and 1s provided with marginal -fastening prongs 12 which are suflicient in length v`to project clenchedon the outerside thereof as shown Arranged within theV shell- 11..is [a substantia-ll'y flat disk 13 which will be hereinafter referred to as a locking disk, and which is peripherally secured tothe concave face of the convex shell 11 by a\line of solder or similar cement. The locking disk is provided with a centrally locatedv opening 15 of sufficient cross dimension to receive the l locking rstud 9, the head of vwhich latter projects a slight distance beyond the bottom face of the locking disk. Arrangedupon the bottom faceo-f the locking disk is a pair of oppositely disposed resilient lips 16 the freeends of which engage the locking stud in the rear of its retaining head, the latter engaging the lips when the operation of mount-ing the seal has been completed and positively preventing the withdrawal of the v locking stud. j

In applying the seal, the concave shell 11 containing the locking disk 13 is placed with its prongs engaging the inner face of the through the envelop body and clenched 'on the outer side thereof. The shell 7 which is of4 less diameter than the locking disk 13 is now ,placed in engagement with the outer face of the envelop flap and firmly pressed thereagainst, this operation causing the prongs 8 to pierce through the flap when The prongsv are pressed 15. When the seal ha's been ation of my invent-ion will be easily under- GQv through the body ofthe envelop and be stood without a more extended explainaait-ion7 it being understood that various Changes may be. mede in the minor details of con.1 stiucsion within the scope of the appended claim.

What is claimed istw The combination iii an envelop seal7 of a, pail` of' shells, a stud attached to one of said shells, n. head formed upon said stud and connected theie'o by a tapered neck, a disk seciiied to the other of seid shells and pi'ovicied Wih en, opening for receiving said head, :i poil of leaf springs secured to siii disk and having their free ends in Contact Wiili each otliei", grooves formed in the tei'- miimls of said leaf springs and producing a Liioulzii' aperture, saidsprings adapted t0 commet with the tapered neck of the head, and hold the shells rigidly With respect to suoli other.

In testimony whereof, I affix my signaiui'e, in presence of two Witnesses.
